Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, a cable with dual insulation effect for power equipment includes a conductor 1, and an insulation protection sleeve 2 disposed at a radial outer position relative to the conductor 1, the insulation protection sleeve 2 mainly functions to insulate the conductor in the cable from the surrounding environment or adjacent conductors, a filling layer 4 disposed at a radial outer position relative to the insulation protection sleeve 2, a flame retardant layer 5 disposed at a radial outer position relative to the filling layer 4, an insulation isolation component 3 disposed on an inner wall of the filling layer 4, and an outer protection sleeve 6 fixedly mounted on an outer wall of the flame retardant layer 5.

Insulating isolation subassembly 3 sets up between four groups of insulating protective sheath 2, and insulating isolation subassembly 3's material is the polyethylene board, insulating isolation subassembly 3's thickness is the same with the clearance width between every group insulating protective sheath 2, insulating isolation subassembly 3's length is the same with insulating protective sheath 2's length, on original insulation construction's basis, it carries out the dual insulation protection to set up insulating isolation subassembly 3, when cable long-term operation back produces a large amount of heats and causes the destruction to insulating sheath, insulating isolation subassembly 3 plays a role, carry out insulating isolation to each conductor, prevent contact each other between conductor and the conductor, guarantee the normal use of cable.

The filling layer 4 is the mica tape, and the mica tape has good high temperature resistance and fire resistance, and fire-retardant layer 5 is chloroprene rubber, and chloroprene rubber has good physical and mechanical properties, and is resistant to oil, heat-resisting, resistant fire, resistant sunlight, resistant ozone, and acid and alkali-resistance can fine carry out the fire-retardant protection work of cable, and outer protective sheath 6 is the polyvinyl chloride mixture, is difficult for by acid, alkali corrosion, and the heat resistance is stronger.

To sum up, this power equipment is with cable that has dual insulation effect on the basis of original insulation construction, sets up insulating isolation component 3 and carries out dual insulation protection, when producing a large amount of heats and causing the destruction to insulating cover after the cable long-term operation, insulating isolation component 3 plays a role, insulates each conductor and keeps apart, prevents to contact each other between conductor and the conductor, guarantees the normal use of cable, compares in the past, has also promoted the security of using when having promoted insulating effect.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
